WELCOME TO SHELDON REFUGE

Sheldon National Wildlife Refuge was originally established as two separate areas, having different names and different jurisdictions. The original Sheldon National Antelope Refuge was established in 1931 and contained more than 34,000 acres. The Charles Sheldon Antelope Range, or Game Range, was established in 1936 and comprised over 540,000 acres; the two areas were combined to form what is now the Sheldon National Wildlife Refuge, comprising over 575,000 acres under the sole administration of the U.S. Fish and Wildlife Service.

A VARIED LANDSCAPE SUPPORTING OVER 270 SPECIES OF WILDLIFE

The refuge is primarily high, semidesert country typical of the Great Basin, characterized by large tablelands and rolling hills. These areas are interrupted by narrow valleys and canyons bordered by precipitous rocky rims. Elevations range from 4,100 to 7,200 feet above sea level.

Habitat types include big and low sagebrush areas, mountain mahogany, and bitterbrush in the mountains above 6,000 feet. Other important types include alkaline lakes, marshes, grassy spring-fed meadows, greasewood flats, juniper covered uplands, and aspen stands in the more secluded canyon areas. Each of these areas supports its own particular wildlife species.

ENJOYING THE REFUGE'S WILDLIFE

The study of wild animals in their natural habitats has become an increasingly popular pastime for many people. Due to the large expanse of the Sheldon area, viewing wildlife on Sheldon National Wildlife Refuge can be greatly enhanced by a pair of binoculars or spotting scope. Binoculars enable one to observe all animals from a distance - mule deer and antelope to small birds - without disturbing the animals.

Wildlife species in this brochure are grouped into five categories: birds, mammals, amphibians, reptiles, and fish.

FOR YOUR SAFETY

Because of the isolation and vastness of the refuge, inquiries should be made at refuge headquarters about current road conditions before travelling to the more remote portions of the refuge - especially in the winter and spring months. Refuge headquarters is located in Lakeview, Oregon, with a subheadquarters at Dufurrena, 30 miles west of Denio, Nevada.

BIRDS

Bird populations vary greatly in numbers and species according to seasons. Heavy migrations of waterfowl and waterbirds visit the refuge during spring and fall with a portion of these remaining through the breeding season. During the summer months, a wide variety of the smaller birds and birds of prey are present, attracted to the numerous cliffs and spring-fed riparian areas. The best opportunity to observe the greatest diversity of bird life on Sheldon Refuge is from May to October.

The following bird list contains 192 species, plus 27 accidental species that have been recorded since the refuge was established. It is not considered final as observations by many people continue to add to the quality and accuracy of the list. We encourage and appreciate these observations and ask that they be reported as soon as possible to the Lakeview or Dufurrena offices.

A few abbreviations have been used pertaining to the birds found on Sheldon to assist the observer in determining status and seasonal abundance. Names are in accordance with the Sixth (1983) American Ornithologists' Union Checklist of North American Birds as amended.

Refuge personnel and visiting professional and amateur ornithologists have contributed the observations for this list. It is undoubtedly incomplete; many other species probably use the refuge at least occasionally. Contributions of confirmed sightings are welcome.
